Full-wave, finite element analysis of irregular microstrip discontinuities
TL;DR: Finite element expansion currents are used to formulate a full-wave analysis of microstrip discontinuities as mentioned in this paper, and the analysis of fairly irregular structures is possible, including radiation and surface wave effects as well as coupling between closely spaced junctions.

The Effect of Complex Modes at Finline Discontinuities
Abbas Omar,Klaus Schunemann +1 more
TL;DR: In this article, the effect of ignoring complex modes on finline discontinuity problems is investigated, and it is shown that the modal energy distribution at both sides of the discontinuity may be greatly affected by overlooking complex modes, even if they are not strongly excited.

An efficient algorithm for the three-dimensional analysis of passive microstrip components and discontinuities for microwave and millimeter-wave integrated circuits
A. Hill,Vijai K. Tripathi +1 more
Abstract: A numerical technique for the full-wave analysis of shielded, passive microstrip components on a two-layer substrate is presented. The distinct feature of the technique is an efficient formulation for establishing the system matrix in the moment method procedure which allows the derivation of the elements of any large matrix by a linear combination of elements in a precomputed index table. The table is obtained from a two-dimensional discrete fast Fourier transform. In the moment method procedure, the two-dimensional surface current is represented by locally defined rooftop functions. The effect of the resonant modes associated with the metallic enclosure on the numerical procedure is examined. In order to demonstrate the features and the accuracy of the technique, numerical results for a microstrip open end and for a right-angle bend with and without the compensated corner are computed by using the resonant technique and are compared with other published computational and experimental data. >

Theoretical of and Experimental Investigation Finline Discontinuities
TL;DR: In this article, the dominant and first-five higher order modes in a unilateral finline were precisely described from a thorough spectral-domain approach, and coupling coefficients between eigenmodes at a discontinuity that have to be introduced into the scattering matrix formulation were directly computed in the spectral domain, and consequently the equivalent circuit parameters of the discontinuity were determined Finafly, finline discontinuities often used for impedance transformation are investigated and a good agreement between theoretical and experimental results is reported
